Nearly all manufacturers do not advertise/exhibit their product measurements? Why?


After my Audio Science Review review forum, it became apparent that nearly the only way one can determine the measurements of an audio product is wait for a review on line or in a publication.  Most equipment is never reviewed or is given a subjective analysis rather than a measurement oriented review.  One would think that manufacturers used tests and measurements to design and construct their products. 

Manufacturers routinely give the performance characteristics of their products as Specifications.  Those are not test measurements.

I searched the Revel speaker site for measurements of any of their speakers and could not find any.  Revels are universally lauded for their exceptional reviewed measurements.  Lack of published manufacturer measurements is true for nearly every speaker manufacturer I've searched for on line, perhaps several hundred.   Same is true for amps, pre-amps, DACs, transports, turntables, well you get the picture.  Do they have something to hide?   I doubt the good quality products have anything to hide but poor quality products do.  

ASR prides itself in providing "true" measurements that will aid in purchase decisions.   Why don't the manufacturers provide these measurements so that reviewers can test if they are truthful or not?

Then there are the cables and tweaks for which I suspect that there are inadequate tests available to measure sonically perceived differences but which objectivists believe don't exist or are "snake oil."  

Well, please chime in if you have some illuminating thoughts on the subject.   

I would have loved to see manufacturers measurements on my equipment and especially those that I rejected.

I wasn’t asking you about if you saw that review or not. Now answer my question - Would you like me to post that detailed photo and explain where he went totally wrong?!

Of course you should. But you said you dont care about measurements, so how can you say where he went wrong? You are also not qualified like he is. I will have you know that he is a qualified engineer. Are you?

I asked Paul at PS Audio to explain how Amir's testing of the PS Audio Power Plant showed the device did nothing at all.

Why would you trust the owner of PS audio to give an unbiased response to  criticism? Couldn't you find someone else? No company owner is ever going to speak badly about their own products even if there is something terribly wrong with it. 

There is plenty of horrendously overpriced hifi equipment out there much of which doesnt even work. The ASR group works tirelessly to expose these charlatans. Be grateful.

Pathetic.

@bigtwin

Sure. I get it too. Amir is keen on destroying established audio companies or anyone who doesn’t pay him for a review! Either that, or he’s just exceedingly incompetent. Perhaps even both!!

Check out my systems page for a new photo I uploaded - It showcases alarming differences in test results. Amir recently reviewed an IEM for a little over 2 grand. The folks on Head-Fi know what they’re talking about. Also consider the overblown levels and disgusting EQ Amir implements to "fix" them!! Killing off all brilliance (upper treble) and destroying what is left of the response the driver units can muster.

Hell, I think Amir would have great difficulty tuning an integrated car system stereo - with only treble, bass, and balance to set!! left to right so + or  - the dB !!

To be honest, I'm starting to think so.

A secondary account; to defend himself. Kind of like an underground bunker. But he's throwing beanbags...not rocks.
